APPARATUS FOR LEVELING AND SQUARING STONE.

SPECIFICATION forming part of Letters Patent No. 397,286, dated February5, 1889.

Application tiled November 20, 1888. Serial No. 291,380. (No model.)Patented in Germany September 29, 1887, No. 48,761, and in FranceNovember 11, 1887, No. 186,925.

To all whom it 711.11g (ZUHMJ'IL:

Be it known that l, MAX lll-iNsEL, of Christianstadt on Bober, Kingdomof Prussia, and Empire of Germany, have invented certain new and usefulimprovements in Apparatus for Leveling and Squaring Stones, (for whichLetters Patent were granted to me in Germany, No. -:L.3,7t;l, datedSeptember 20, 1887, and in France, No. 1Sti,925, dated November 1.1,1887,) of which the following is a specification.

The object of my invention is to provide a new and improved apparatus ofsimple construction to be used for leveling and squaring stones eitherin blocks or in thequarry, which apparatus can also be used for locatingpoints in making stat-nary.

The invention consists in the combination, with a standard having atripod-base, of a 1'0- tative sleeve on said standard, ahorizontallysliding rule in said sleeve, and a vertically sliding rulein the end of the horizontal rule; and the invention also consists inthe combination of parts and details, as will be fully described and setforth hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure l is a front elevation of myimproved apparatus for leveling and squaring stones. Fig. 2 is an endview of the same. Fig. 3 is a sectional plan view, parts being brokenout. Fig. 4 is a detail face view of the lower end of the vertical rule.Fig. 5 is an edge view of the same. Fig. 6 is a side view of my improvedapparatus, showing the manner in which it is used for fixing an inclinedsurface on a block of stone. Fig. 7 is a side view of the same, showingthe manner in which it is used for fixing a level surface in a quarry.Fig. 8 is a side view of my improved apparatus and a block of stone,showing the manner of using the same in locating points. Fig. 9represents a model from which the points are taken.

Similar letters of reference indicate corresponding parts.

The base A is provided with three legs, A, in the lower end of each ofwhich an adj usting-screw, A is held, the lower ends of which screws arepointed. On the standard B 011 the base A a sleeve, C, is mounted toturn,

which can be locked in place by a binding screw, 0. Said sleeve 0 isprovided with laterally-projecting head D, and in the same a rule orstraight-edge, E, is mounted to slide horizontallythat is, in a plane atright angles to that of the standard B. One end of said rule E issupported by guide-pieces F on the upper end of an inclined arm, F,projecting from a sleeve or collar, 3r, mounted loosely on the standardB and resting on the base A. The upper end of the rod F is braced by arod, G, fastened to the sleeve G. The head D is also provided with abinding-screw, H,

for locking the rule in place. On one end of the rule E a guide-box, K,is fixed, which is provided with slots for guiding the straightedge orrule L at right angles to the straightedge or rule E, said box beingprovided with suitable binding-screws, K, for locking the rule L inplace. The rule L is provided at its lower erd with an adjustablepointed leg, N, and with a small spirit-level, M.

Below the rule E a circular disk, R, is held horizontally on the sleeve0, the upper surface of said disk being provided withprotractor-subdivisions, so as to facilitate adj usting the rule at anydesired angle in the horizontal plane.

The apparatus is used in the following manner: hen it is desired toobtain a level surface on a block of stone, the instrument is placedupon said stone, and by means of the screws A in the base is so adjustedthat the standard B stands vertically and the rule E is horizontal,which is determined in the usual manner by a spirit-level. The rule L isat right angles to the rule E, and is so adjusted that the point of itsadjustable leg N will be at the desired level or plane. sleeve 0 on theshaft B, or by shifting the rule or straight-edge E longitudi nallyinsaid sleeve, any number of points can be fixed on the stone, all ofwhich points are on the same level. All that is necessary is to cut awaythe stone between said points, care being taken not to destroy thepoints found.

Fig. (3 shows the method of finding points in the manner described, thestandard B being at an inclination; but in all cases the rule E must beat right angles to the standard B, and

By turning the I the rule L at right angles to the rule E and parallelwith the standard 13.

Fig. 7 shows a method of usin my improved implement in a quarry for thepurpose of finding a true and level surface, the manner of using; itbeing prz'letieally the same as that described above.

Figs. 8 and 9 show the manner of using the implement in making statuary.The model is plaeed in a eertain position, and certain points a (t onsaid'model are determined. Their distanee from the end of the rule E ismeasured by means of the rule L. At; said points (I, (1/ on the bloek olstone the stone is cut away nnt il points are found which are the samedistanee from the end of the rule E as are the eorresponding points onthe model. In this manner all the neeessnry {mints ol' the model can befixed on a blocdc of stone, whereby the making ol statuary is greatlylaeilitated.
